## Applied Mechanics and Graphic Statics A smooth cylinder lying on its convex surface remains

In stable equilibrium
Out of equilibrium
In unstable equilibrium
In neutral equilibrium

## Applied Mechanics and Graphic Statics According to Law of Triangle of Forces

Three forces acting along the sides of a triangle are always in equilibrium
Three forces acting at a point, can be rep-resented by the sides of a triangle, each side being in proportion to the force
If the forces acting on a particle be represented in magnitude and direction by the two sides of a triangle taken in order, their resultant will be represented in magnitude and direction by the third
If three forces acting on a, point can be represented in magnitude and direction, by the sides of a triangle taken in order, these will be in equilibrium

## Applied Mechanics and Graphic Statics If the resultant of two forces ‘P’ and ‘Q’ acting at an angle ‘θ’ makes an angle ‘α’ with ‘P’, then tan α equals

P sin θ/P + Q tan θ
Q sin θ/P + Q sin θ
Q sin θ/P + Q cos θ
P sin θ/P - Q cos θ
